Apple's new Face ID technology promises a security revolution for iPhone users — and it also promises to change all of enterprise security, eventually. While Face ID's primary audience consists of consumers who buy iPhones, Apple has created a new paradigm for security with a safer, faster authentication system. Similar technology eventually will filter down to devices of all kinds and enable organizations to provide their employees and customers with more secure experiences, protecting their data and keeping cybercrooks at bay.
Face ID, introduced by Apple at its product launch on September 12, is a major advance in biometric authentication, both over Touch ID (fingerprint) authentication that Apple devices have used until now and over other facial recognition systems. Apple says Face ID is so accurate that the chance of another random person's face being used to unlock your phone is 1 in 1,000,000 — much better than the 1 in 50,000 unlock error rate for Touch ID. Face ID bests other facial recognition systems as well; it's the first consumer-oriented 3-D facial recognition system, beating out systems in devices such as Samsung's Galaxy S8 and Note8, which are 2-D recognition systems.
The authentication provided by Face ID certainly will prove sufficient for use by organizations as an authentication method to "prove" that a device belongs to the user. Today, however, many organizations — often because of regulations, such as for apps that can access customer account information, or at least as part of best practices — require two-factor authentication. For most organizations, that means requiring users to input a password (something users know) in order to activate an app or log in to a website from a mobile device, coupled with a second authentication factor, such as a biometric marker like a fingerprint (something users are), or a text message sent to a user's device, which consists of a code that the user must enter into a site or an app (something users have) in order to access it.
The fact that Face ID is superior to passwords as an authentication method should come as no surprise. The vast majority of major data breaches in recent years (think Sony, Target, major banks, etc.) were due to compromising of login data and password theft. According to a study by Verizon, more than four out of five data breaches are due to stolen passwords or misused credentials; it certainly wouldn't make sense to have such a weak authentication method to access sensitive data when such a strong authentication method is used to secure the device itself!
That's why, I believe, Face ID will be the catalyst that sets off a real revolution in data authentication. If Apple can implement such a strong authentication method for its devices, organizations will be searching for something at least as strong to authenticate their data on all devices out there that don't use Face ID.
The fastest-growing solution for user authentication in enterprises is phone authentication, in which a mobile device — instead of a hardware token or a password — is used as an authenticator. Organizations that have sought higher levels of security have already ditched passwords, turning instead to authentication systems based on devices, which are considered more secure than passwords and, for an increasing number of organizations, their primary authentication method in a two-factor authentication scheme.
Seeking better security, more organizations will increasingly dump passwords for device authentication, a system that can be used on any mobile device; the greater security provided by Face ID will, I believe, inspire many organizations to reconsider how they approach authentication, and opt for something more secure, even on devices other than the newest iPhones.
Fingerprints have often been used as a second factor in a two-factor scheme, but now that second factor has gotten a major upgrade, two-factor authentication based on devices and used with Apple devices that support Face ID will present a formidable challenge — enough to discourage hackers from even trying to breach an Apple device. While Face ID currently is strictly limited to some Apple devices, it's just a matter of time until 3-D face recognition as an authentication method trickles down to the rest of the industry, as the industry follows in the path of market leader and innovator Apple.
Combining proven device authentication systems with Face ID truly is a game changer — a revolution, even — and companies seeking to improve their security systems are going to be very attracted to this winning combination. Long live that revolution, I say.
